With the transaction, Amplify Interactive, located at 107 S.E. Washington St. on the central eastside, has retired its brand and now operates as the Portland office of Add3.

Ben Lloyd, Amplify's founder and president, has been named Add3 Principal and is heading the company's Portland operations. Add3 plans to continue hiring in both its Seattle and Portland hubs.

Add3 is on-track to post revenues of $10 million for 2013, not including Portland contributions. The company was recently included on The Inc. 500/5000 list of America's fastest-growing private companies.

Portland office clients include Tripwire, Inc., and Janrain. Seattle clients include Costco and the Space Needle.

"This is a significant step for Add3, as there's tremendous value to having a physical presence in a dynamic market like Portland and because this move brings some exceptional new talent and search expertise to Add3," said Paul Uhlir, Add3 chief executive said in a news release. "We are thrilled to welcome Ben Lloyd and his team them to the Add3 family and look forward to working together to serve our clients and continue growing our combined practice."

Amplify was founded in 2003; Add3 was incorporated in 2011. Uhlir and Lloyd have known each other for several years.

Lloyd is recognized as a pioneer in Portland's search engine and online analytics community and is among a handful of people credited with launching the local industry group SEMpdx.
